My buddy has a 91 Mariah that his parents own and has been in his family since it was new. Last year on the lake something happened and they must of hit something and it sheared the prop right off.
Told him I’d give him a hand fixing it.

Plan is to remove the shaft, remove the rudder and check it, inspect the strut, replace strut bearing, repack the rudder if it is ok, replace the prop and shaft and repack the shaft.

My question is on a new prop shaft, do they fit the old coupler? I noticed on skidim it was asking for shaft length, shaft diameter, and coupler diameter. Can the new shafts can be installed from the bottom of the boat? I assume I don’t have to pull the motor to install the shaft? Any input is appreciated.
